----------------------------------------
Summary: AvroParquetReaders does not work with ReflectData
Key: FLINK-26349
URL: https://issues.apache.org/jira/browse/FLINK-26349
Project: Flink
Issue Type: Bug
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Affects Versions: 1.15.0
Reporter: Dawid Wysakowicz
Fix For: 1.15.0
I tried to change the {{AvroParquetFileReadITCase}} to read the data as
{{ReflectData}} and I stumbled on a problem. The scenario is that I use exact
same code for writing parquet files, but changed the reading part to:
{code}
public static final class User {
private final String name;
private final Integer favoriteNumber;
private final String favoriteColor;
public User(String name, Integer favoriteNumber, String favoriteColor) {
this.name = name;
this.favoriteNumber = favoriteNumber;
this.favoriteColor = favoriteColor;
}
}
final FileSource<User> source =
FileSource.forRecordStreamFormat(
AvroParquetReaders.forReflectRecord(User.class),
Path.fromLocalFile(TEMPORARY_FOLDER.getRoot()))
.monitorContinuously(Duration.ofMillis(5))
.build();
{code}
I get an error:
